An article from Suicide Prevention Resource Centre discusses the below:
Effective suicide prevention is comprehensive: it requires a combination of efforts that work together to address different aspects of the problem. The model above shows nine strategies that form a comprehensive approach to suicide prevention and mental health promotion.
Each strategy is a broad goal that can be advanced through an array of possible activities (i.e., programs, policies, practices, and services). This model of a comprehensive approach was adapted from a model developed for campuses by SPRC and the Jed Foundation, drawing on the U.S. Air Force Suicide Prevention Program.
